Sen ge survey Guidance document Summary:
The first item discussed was the draft laboratory report on the nine POTW test sites.
Prior to the meeting, NRC and EPA staff reviewed the statistical analyses performed by Lee Abramson and Scott Telofski to determine which data had been used in the analyses.
It was determined that the results of sample l
reanalysis conducted in April 1998 had not been utilized in the statistical analyses.
However, a review of the data from the reanalyzed samples showed j
only minor changes from.the earlier data used in the statistical analysis.

I..
l i.
l The subcommittee agreed that it was not necessary to revise the statistical l
analyses.
It was requested that NAREL review the data concerning ash samples I
from the pilot study as a quality assurance measure.
This task entails checking the dry and wet ash sample results for gross alpha and gross beta measurements.
l Regarding the use of U.S. DOE / Environmental Measurements Laboratory's (EML)
Quality Assurance Program (OAP) studies as a quality assurance mechanism during the sewage survey. NAREL plans to complete its review before the next subcommittee meeting. The NAREL review will also address the ability of OAP results to be a good indicator of laboratory performance for the matrices and radionuclides encountered in the study.
Lee Abramson and Scott Telofski briefed the subcommittee on their recent telephone conversations concerning the statistical analyses.
It was agreed that better estimates of uncertainty in the data are needed, which would include estimates of the sample inhomogeneity and total error.
NAREL planned to continue their analyses to bound uncertainties other than counting error.
i such as random error.
The subcommittee agreed that the test site report should include a narrative that explains the sources of uncertainty in the data the differences between ORISE and NAREL standard analytical and reporting procedures, and the results of the EML QAP comparison study.
On the topic of clearance from the Office of Management of Budget (OMB) for the sewage survey. Tony Huffert informed the subcommittee that OMB approved the sewage survey on June 17. 1998.
The expiration date for the approval is June 30. 2001 and the OMB number is 3150-0189.
One of the issues that concerned OMB during its review was the notification of survey participants about survey results from their POTW. while maintaining overall confidentiality of the survey.
Mary Pat Siemien and Alan Margolis provided legal perspectives and responses to the subcommittee's questions about Federal laws that may be applicable to this issue.
I Bob Bastian discussed the reference radionuclides concentrations that NRC and j
EPA developed in a separate document.
A new version of the document should be available for the September meeting of the full ISCORS committee.
It was agreed that the report format should follow the MARSSIM recommendation for i
reporting values that are less the MDC.
Loren Setlow requested that ORISE and i
NAREL send him sample analysis data in electronic format so that ash and sludge data could be separated for further analyses.
A goal is to obtain a range of radionuclides values for sludge and ash for use in the reference radionuclides concentration document.
c f
. l Regarding progress on completing the Quality Assurance Project Plan (OAPP) for l
the survey the subcommittee agreed that additional information on the sources of uncertainty in the sample results is needed and that new sample handling procedures will need to be incorporated into the OAPP once they are established.
Tony Huffert updated the subcommittee on the status of a letter that NRC is preparing for Agreement States participation in the sewage survey.
EPA will be sent a copy of the letter once it is issued. so that it could be used as a j
model for a similar letter to non-Agreement States.
Jill Lipoti stated that i
she has a list of 25 State volunteers for the survey, which will be sent to Behram Shroff for handling.
i The dose modeling working group met on June 22. 1998 at EPA offices in i
Washington, DC.
Loren Setlow summarized the results of the first meeting.
which included a review of previous sewage dose modeling studies, a discussion of risk assessment guidance that supports EPA's ~503" regulation on heavy metals and organic compounds in biosolids, and use of exposure pathways therein as starting point for radiation dose modeling.
The meeting also addressed the development of Data Quality Objectives and a OAPP for the dose modeling effort.
The next meeting of the dose modeling working group will be held in July.
The final topic discussed was the POTW guidance document.
EPA's contractors have reviewed the document and prepared comments for the subcommittee's review.
A suggestion was made to include a section of Frequently Asked Questions in the POTW guidance document.
Meeting participants scheduled the next subcommittee meeting for August 4th at NRC offices in Rockville Maryland.
At this meeting. the subcommittee will discuss the report on the test sites, the list of POTWs to be sent the questionnaire comments on the POTW guidance document, the results of the dose modeling working group meeting, and the status of the table of reference radionuclides values.
Action I'tems:
1.
Review data concerning ash samples from the pilot study as a quality assurance measure. This task entails checking the dry and wet ash sample results for gross alpha and gross beta measurements to ensure consistency in reporting the type sample (wet or dry) used ior analyses by both labs. (Saunders).
l L___.m_______._______.-___-
. l 2.
Provide range of radionuclides concentrations separately for sludge and for ash for use in public reference document.
Both laboratories (0 RISE l
and NAREL) were requested to provide information to Loren Setlow on each lab's pilot study minima and maxima results for each radionuclides l
tested. The report should include separate minima and maxima for each radionuclides tested for sludge, and for ash, and include the MDC for each minimum and maximum reading.
Results should be reported to one significant figure.(Saunders and Condra).
3.
Review the EML 0AP studies as a quality assurance mechanism during the sewage survey. The review will also address the ability of QAP results to be a good indicator of laboratory performance for the matrices and radionuclides encountered in the study (Wisdom).
4.
Revise the draft report to include a narrative that explains the sources of uncertainty in the data, the differences between ORISE and NAREL standard analytical and reporting procedures, and the results of the EML 0AP comparison study (Al1).
5.
Complete the reference radionuclides document before the full ISCORS committee in September.
The report format should be revised to follow the MARSSIM recommendation for stating values that are less than the minimum detectable activity or amount (Setlow).
l 6.
Revise the OAPP to include additional information on the sources of uncertamty in the sample results and new sample handling procedures (Setlow).
7.
NRC is to complete its review of the Agreement State letter and send EPA a copy of the letter once it is issued (O'Brien).
8.
Jill Lipoti is to send Behram Shroff a list of 25 State recommended test sites for the survey.
9.
The dose modeling working group is to meet in July (Mo. Powers and Setlow).
10.
Review EPA contractor comments on the POTW guidance document (All).
)
l 11.
An open item from the previous meeting is for D00 and DOE reps to submit lists of POTWs associated with their agencies' facilities (or lists of the D00 and DOE facilities so Bob Bastian can identify the POTWs).
